Full DC inverter TechnologySunrain DC Inverter heat pumps, including the advanced air-to-water heat pump, are designed to deliver remarkable energy savings for both heating and hot water production. With their high Seasonal Coefficient of Performance (SCOP) levels, these heat pumps offer exceptional efficiency and sustainability. In comparison to traditional heating systems such as boilers, air-to-water heat pump can reduce energy consumption by 30% to 50% over a single winter, leading to substantial cost savings for users. By harnessing renewable energy from the air, the heat pump minimizes reliance on fossil fuels and significantly lowers carbon emissions, making it an environmentally-friendly choice.
EVI Monoblock Air Source Heat Pumps Working Principle Diagram
Sunrain provides the monoblock heat pump with an integrated main circulation pump. During installation, the installer needs to ensure the proper connection of the heat pump with other components, such as the buffer tank (for space heating/cooling), storage water tank (for domestic hot water), and water pumps (for circulating space heating/cooling water and domestic hot water). Additionally, external fittings are required, including the safety valve, water refill valve, and hot water valves (three-way valve). It is necessary to incorporate a temperature sensor in the storage water tank. Furthermore, an additional electric heater can be installed in either the DHW tank or the buffer tank, allowing it to receive control signals from the heat pump.
Standby programs for user selection:Seven modes1)-Hot water mode 2)-Fan coil heating mode
